The MAX8630ZETD25+ is an LED driver IC, which belongs to the power management IC (PMIC) family. It is specifically designed for powering the LEDs with a constant current, ensuring that the light intensity remains constant even when the battery power fluctuates. This IC is ideally suited for automotive, general lighting, router networking, measurement and smart home applications.
This device is a high-performance LED driver, featuring a constant current and voltage, as well as powerful output current. It provides a constant current source, able to drive up to 1 A LEDs from a supply voltage ranging between 5 V–25 V. It has a “thermal protected” operating temperature range from -40 °C to +125 °C, which makes it ideal for use in high temperature applications.
Additionally, the MAX8630ZETD25+ features an internal under voltage lockout circuit to protect the IC from run-away conditions. This IC integrates several safety features, such as over-current, over-temperature and short-circuit protection, making it safe in any application.
Application Field and Working Principle
The MAX8630ZETD25+ is a useful device for driving high - power LEDs. It has a wide operating temperature range and is suitable for automotive applications, such as dashboards and headlight applications, where these two parameters become major factors in device selection. The output current can be adjusted with an external resistor and a wide range of output current, from 4 mA to 1 A, is available.
The MAX8630ZETD25+ LED driver IC operates using a constant current source control topology. The device consists of two parts - an error amplifier and a current source. The error amplifier controls a transimpedance amplifier, which converts an input current into a voltage. A compensation network is connected within the power loop to give improved regulation. The output voltage is controlled by the error amplifier and the output current is limited by the current source.
The device features a low shutdown current ( 0.5 μA) and includes enable and disable functions. The enable and disable pins can be used to enable and disable the device, while the LED Driver IC is powered. The device also features an Internal Reset output2 that can be used to indicate a fault condition. Additionally, the MAX8630ZETD25+ provides a Power Good output that indicates the presence of an output voltage.
In conclusion, the MAX8630ZETD25+ is an extremely versatile device, ideal for many applications, including automotive lighting. It provides full over-voltage and over-temperature protection, as well as a range of safety features, making it a secure and reliable choice for LED drivers.
